Mine is defiantly the Eastern Grey Tree frog because his call is the same as and Eastern Grey Tree frog and different from the cope's grey tree frog. I seriously have about 20 mated pairs of eastern grey tree frogs that come to my pool every year. At one time I had 25 eastern grey tree frogs on my pool deck. no joke. They are everywhere. in my windows, hose, everywhere. I have to check the grill before I turn it on so I don't cook one. That's how many I have around my yard. a cooked frog smells horrible.
